The rain has come back, which is generally welcomed here in Northern California. Now that I think about it, Southern California probably welcomes the accompanying high elevation snow pack more as most of their water originates from the snow melt in Northern California.
This period of rain means me going to the well (aka portfolio of unused images) for these blog posts. I have been processing these images of flowers and isolating them by masking the background into black. The interesting result for me is noticing the “errors” in selecting the aperture. The aperture used for most of these wildflower photographs is between 2.8 and 3.5, enough to blur the green grassy background. The problem with those aperture selections is that parts of the flower become out of focus and in this case the outer edges of the flower petals. Aperture consideration in the future should take into account the finished photograph. If the intent is to isolate on a dark background, the aperture can be less wide open f/8-11 should be more than adequate. If the intent is to include the background, f/2.8-3.5 should be fine.
Plant Notes: The flower is commonly known as the Ithuriel’s spear or Grassnut (Triteleia laxa) and is a triplet lily native to California. The plant grows from a bulb known as a corm which resembles and allegedly tastes like a potato. As triplet lilies, all parts of the flowers come in threes.
EXIF data: Nikon D7000, spot metering mode, ISO100, 35mm (prime lens), f/3.5, 1/30 sec
